Description

Electronic lock and clutch mechanism

The invention relates to an electronic lock, in particular to an electronic lock with a simple clutch mechanism and saving space.

Generally speaking, the electronic lock uses a motor as its power source, and then transmits the torque output by the motor through a gear set, thereby driving the clutch mechanism of the electronic lock to move and then engage or disengage the lock assembly. When the gear set is driven forward by the motor, the pushed structure provided on the gear set can drive the clutch mechanism to engage the latch combination of the electronic lock. As a result, the torsion force received by the handle can be transmitted to the latch assembly, and the user can turn the handle to achieve the purpose of opening the door. When the gear set is reversed by the motor, the clutch mechanism can be separated from the latch combination of the electronic lock by a spring. Therefore, when the handle is subjected to torque, the handle can only idle and cannot transmit torque to the latch assembly. Thereby, the latch combination can maintain the latched state.
